Vector V1 is 6.6 units long and points along the negative x axis. V2 is 8.5 units long and points at +55 degrees to the positive x axis.

Question

A) What are the x and y components of each vector?

B) Determine the sum of vector 1 and vector 2. (magnitude and angle)

I have solved the components for V2, but I am stuck on solving for the components of V1 because I can't figure out how to solve for the angle of V1.

Answer 1

huh? v1 = <-6.6,0>

don't get so bogged won in formulas that you fail to recognize simple geometry!

If you must rely on the formulas, note that θ=180°

Answer 2

I don't now
